INK-WELL ATTACHMENT.

Specification of Letters Patent.

Application filed November 29, 1913. Serial'No. 803,750.

To all whom it may concern:

Be it known that I, ADELBERT D. EvANs, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented new and useful Improvements in Ink-l/Vell Attachments, of which the following is a specification.

This invention relates to ink well attachments; and it has for its primary object the provision of means for preventing the pen from being inserted beyond a predetermined position in the ink.

.Another object of the invention is the provision of a device of this character which will automatically accommodate itself to the level of the liquid in which it is mounted and one which will include a shutter or cutolf actuated under the direct engagement therewith of the pen.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed. f

In the accompanying drawings: Figure 1 is a vertical section through an ink well, showing the application of the attachment thereto; Fig. 2 is a similar view, showing the shutter actuated under the action of the pen so as to prevent the latter from being inserted beyond a-prescribed or predetermined depth in the ink; Fig. 3 is a horizontal section on the line 33 of Fig. 1; and Fig. 4: is a perspective view of the sliding cutoff.

The device comprises a tube 1 split vertically or folded or rolled so that its vertical edges are spaced to permit of the formation therebetween of an intervening continuous vertical guide slot 2 and adjacent thereto the tube has one of its walls formed with a vertical series of ratchet teeth 3. The upper end of the tube is fitted on the reduced end 4 of a hollow sleeve 5, the latter having its bore widened into internally flared upper walls 6 to facilitate the guiding of the pen into the tube. The sleeve is adapted to be secured in an opening 7 in the top 8 of an ink well, such as the one shown herein at 9. However, I wish it to be understood that the form of well or container is not essential to an operation of the device to permit the pen to be furnished or supplied with a desired quantity or predetermined supply of ink.

The tube 1 is embraced by companion sections 10 of a vertically movable collar, and

tion. Theopposite'terminals 14; of the collar sections are connected together by a rivet 15 wh ch forms a pivot-for a vertically tilting shutter-or valve 16, whose shank or extension 17 is fitted between the portions 14:. One of the collar sections is provided with a bracket 18, which is connected to an extension 19 of the valve or shutter 16 by a spring 20, and under the oifice of the latter, the valve is normally held across the tube, as will be understood. 7

The shank of the valve is adapted to extend through and to travel in the verticalv slot 2. The said shank of the shutter or valve'is provided with an attaching portion 21, which is secured to a float 22. The said shank of the valve or shutter is provided integrally with the extensions 19 with a stop tooth 23 and under the action of the spring 20, said tooth is normally held out of engagemeOnt with the adjacent ratchet teeth of the tu e.

. From this construction, it is obviously understood that the floats 12 and 22 of the vertically movable and tilting shutter constantly seek the level of the fluid contained in the well and that when the pen is inserted in the tube and the pressure thereof brought to bear against the shutter, the valve 16 of the latter will open only to such degree or position as may be necessary to furnish the pen with the proper amount of ink. hen the valve or shutter is tilted by bringing the weight of the pen to bear thereagainst the tooth 23 will coact with an adjacent tooth on the tube 1 and, as a consequence thereof the tilting action of the valve will be limited.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be Patented Apr. 6, 1915'.

resorted to without departing from the principle or sacrificing any of the advantages of this invention as claimed.

I claim:

1. An ink well provided with a tube, a float, a valve supported by the float and mounted for tilting movement, and means for limiting the tilting movement of the valve therein.

2. An ink well provided with a tube, a float associated with the tube and movable thereon respectively on the rise and fall of liquid Within the well, a valve mounted for tilting movements upon the float and disposed within the tube, means on the valve, and means on the tube, the latter coacting with the first means to limit the tilting movement of the valve.

3. An ink Well provided with a tube, a float associated With the tube and movable thereon respectively on the rise and fall of liquid within the Well, a valve mounted for tilting movements upon the float and disposed within the tube, means on the valve,

means on the tube, the latter coacting with the first means to limit the tilting movement of the valve, and means for holding the coaeting first and second means normally inactive relatively.

4. An ink well provided with a tube, a float movably supported upon the tube, a valve carried by the float and means to prevent the lowering of the float on the application of pressure of the pen against the valve and to also permit the valve to be tilted to a predetermined position.

In testimony whereof I aflix my signature in presence of two Witnesses.

ADELBEBT D. EVANS.
